CosmosDB PowerShell Module Version

No response

Feature Description

Enable support for Transactional Batch operations in the Azure Cosmos DB PowerShell module, allowing users to execute multiple operations (e.g., create, update, delete) atomically within the same partition key. This would mirror functionality currently available in Cosmos DB SDKs (e.g., .NET, Java, Python, Node.js) via the TransactionalBatch API.

Motivation and Use Case

PowerShell is widely used for infrastructure automation, provisioning, and DevOps workflows. In scenarios where multiple Cosmos DB operations must be performed together, all-or-nothing atomicity is critical to avoid partial state and ensure consistency.

Without transactional batch support, I must either:

• Fall back to stored procedures (which are harder to version and deploy), or
• Wrap SDK logic in external services and invoke them from PowerShell—adding complexity and reducing portability.

Adding native support for transactional batch would:

• Improve consistency and reliability in infra-as-code workflows
• Reduce operational overhead and error handling complexity
• Align PowerShell capabilities with SDK parity for Cosmos DB
